java - Wildfly Eclipselink checkForUnregisteredExistingObject NullPointerException
问题描述
我有一个问题，我无法将简单的对象保存到数据库。该项目最初使用的是 Hibernate，但我改为使用 Eclipselink。
我有其他带有 Eclipselink 的项目，但没有这个配置和这个服务器（Wildfly 10.x）。
我不确定是否会与某些 JBOSS 库发生冲突。
这是错误：

- Wildfly 10.x 与 Eclipselink 2.5.2 添加到模块文件夹中
我尝试了其他较新版本的 Eclipselink，但无法正常工作。
谢谢。
